This is a normal density elastic cement system that allows creating cement with modified elasticity properties. It ensures improved cementing quality for oil and gas wells, especially during Hydraulic Fracturing operations. It possesses enhanced resistance to failure due to changes in Young's Modulus and Poisson's Ratio.

FCS
Chemical description
FCS (FlexiCem) is a multi-component mixture of materials, predominantly of inorganic origin.
Physical properties
Appearance: powder, from gray to dark gray color
Solubility in water: partial
Solubility in water: partial
Properties of cement stone
Density of cement slurry: from 1.8 to 2 g/cm³
Compressive strength after 24 hours at 60°C: not less than 19 MPa
Strength under volumetric compression: 40 – 80 MPa
Thickening time at 60°C: adjustable
Young's Modulus: 1.5 – 7 GPa
Compressive strength after 24 hours at 60°C: not less than 19 MPa
Strength under volumetric compression: 40 – 80 MPa
Thickening time at 60°C: adjustable
Young's Modulus: 1.5 – 7 GPa
Advantages
- The cement stone has increased elastic properties compared to ordinary cement systems and significantly exceeds lightweight cement slurries;
- It has a self-healing ability after deformation. The cement stone is protected from radial cracking during pressuring and well completion operations;
- The cement stone has increased resistance to cyclic loads.
Usage limitations
Operating temperature range from 15°C to 150°C
Packaging and storage conditions
ECS (Elastomeric Cement System) is packaged in flexible containers (FIBC) weighing up to 1 ton, equipped with a double polyethylene liner. The product should be stored in a dry area, away from moisture, open flames, and heating devices. After the bag has been opened, it should be tightly sealed to prevent product spoilage. The product has a shelf life of at least 12 months.
APPLICATION
Under increased loads
recommended for use in cementing technical and production casing strings in intervals with increased loads on the cement stone.
To increase strength
The cement system has a modified modulus of elasticity, which enhances its strength characteristics. Cement stone possesses elastic properties.
For better results
The elastic cement system is characterized by increased sedimentation stability, reduced water loss, and low permeability, which positively affects the results of cementing the interval.
